Create Payment Request API - google-api-nodejs-client

Question

I am trying to integrate the Payment Request API for the Google Pay for Payments using javascript but my code returns a PaymentRequest is not defined error.
Here is my code.
CODE:
const supportedInstruments = [
{
supportedMethods: ['https://tez.google.com/pay'],
data: {
pa: 'abc#gmail.com',
pn: 'abc',
tr: '1234ABCD', // your custom transaction reference ID
url: 'http://url/of/the/order/in/your/website',
mc: '1234', // your merchant category code
tn: 'Purchase in Merchant',
},
}
];
const details = {
total: {
label: 'Total',
amount: {
currency: 'INR',
value: '10.01', // sample amount
},
},
displayItems: [{
label: 'Original Amount',
amount: {
currency: 'INR',
value: '10.01',
},
}],
};
let request = null;
try {
request = new PaymentRequest(supportedInstruments, details);
}
catch (e) {
console.log('Payment Request Error: ' + e.message);
return;
}
if (!request) {
console.log('Web payments are not supported in this browser.');
return;
}
Error Message:
Payment Request Error: PaymentRequest is not defined

Sounds to me like you are testing it in an older browser that simply doesn't support it. Browser support is pretty good these days, but not universal. You just need to do a simple bit of feature detection and wrap your code in an if statement to check the browser supports it:
if (window.PaymentRequest) {
// your payment request code here
}
